the transverse portion. To these plates 31 and to the sleeve 38 there is connected a forwardly extending gauge wheel supporting structure 39 having a gauge wheel 40 at its lower end arranged to be immediately above the forward portion of the working tool 34 so that it will be engaged by the working tool to effect lifting of the gauge wheel upon the working tool being raised to its transport position. The gauge wheel supporting structure 39 has an adjustable stop 4| adapted to abut with the vertically extending beam 33 to adjust the operating depth of the working tool.

It should now be apparent that the vertically extending beam 33 is so, connected to the lifting bails 29 and 30 that the same can be laterally adjusted with relation to the tractor and toward or away from one of the driving wheels 13. Referring to Figure 3, there is shown diagrammatically the location ofthe working tool 34 when in its plowing. position with reference to the driving wheels l3. With the narrow tread type tractors. this lateral adjustment of the working tool becomes necessary. At 43 there is shown a completed furrow. While forming a furrow 44 in which the working tool 34 is located, the tractor drive wheel l3 at the right side of the tractor will run ahead of the ridge thrown up from the furrow on the level unplowed ground and not in the furrow 43. Since the right-hand wheel I3 is not traveling in the furrow 43, it is necessary that some means for the adjusting of the working tools 34 closer to the right-hand drive wheel 43 be provided. By the use of verti ally spaced bails 29 and 32 provision is readily ade for the connection of the tool beam 33 to have this lateral sliding movement and the structure becomes simplified.

As a means for laterally adjusting the tool beam 33 and its working ,tool 34, and for retaining the same in their laterally adjusted position,.there is provided a manual adjustingmeans 45 having an operating lever 46 accessible to the operators station I! whereby the operator may-- move the working tool 34 from one side of the tractor to the other side of the tractor depending upon the direction of movement of the tractor across the field. When the furrowed land is at the right, the working tool 34 will be near to the right-hand drive wheel whereas when the furrowed land is at the left the working-tom 34 will be near to the left-hand drive wheel. 7

This adjusting mechanism 45 is supported on the lower bail and at the left side thereof. In addition to the'lever 46 it includes a quadrant 41 over which the lever works, the lever being pivoted at 48.- The adjusting mechanism 45 is connected to a bracket structure 49 which is in turn welded to one of the leg portions of the lifting bail 30, as indicated at 50. Immediately above the pivot 48 there is provided a rigid extension 5| on the lever 46 which is connected by means of a link 52 to a lug 53 rigidly secured to the sleeve 38. ,It should thus be apparentthat any movement of the lever 46 over the quadrant 41 will effect lateral movement of the sleeve 38 and the tool beam 33. The beam 33 will slide with respect to the transverse portions 3| and 32. On the adjusting mechanism 45 there is provided the usual locking detent means 54 which will serve to retain the tool beam 33 in its laterally adjusted position.

As a meansfor effecting movement of the working tool 34 to a. transport position, there is provided a manual lifting mechanism also accessible to the operator's station H. Said mecha-..

nism includes a lever 56 and a quadrant 51 over which the lever is worked and is lockedin place by a detent mechanism 58. this lever has thereon a'rearwardly extending arm 59 which is connected to-the lower bail 30 by means of a chain 60. As the lever 56 is moved,

, lifting bails be laterally adjusted. By using the vertically spaced lifting bails for the connect-.

ing of the working tool to the tractor the lateral adjusting mechanism may be connected to thebail itself and at the same time in a location Mr V cessible to the operator's station.

While various changes may be made in'the detail construction, itshall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claims.

What is claimed is:

1."
